collected ing chamber 32 by way of conduit 38 leading from check valve37. When plunger 23 moves inwardly the oil is forced up through checkvalve 39 arranged directly over chamber 32 at its inner end, acrossthrough a groove 40 formed in cap 41 secured to casing 42 of the pump,down through conduit 43 and out through pipe 44 which leads to acollecting sump (not shown). Bolts 45 serve to secure cap 41 to casing42.

A pipe 46 is connected to pipe a part of the oil coming from an aperture47 in eccentric 13. When a bore 48 formed in eccentric ring 14registers, during the course of rotation of eccentric 13, with aperture47, the oil will spurt through bore 48 and come out a little above thepump and a little towards eccentric 13, so that the rollers 27 will bein the path of the oil as it is thrown outwardly by centrifugal forces.The arrangement is such that the rollers 27 will be lubricated from bore48 at the time they come in contact with cam 31. i

It is to be understood that various modifications and changes may bemade in the em bodiment herein described without departing from thescope of my invention as set forth in the appended claims.

Having thus described my invention,

What I claim is V 1. In a drivingmechanism, the combination of arotatable eccentric, an eccentric ring therefor, an annular lipextending outwardly and upwardly from said eccentric and forming anannular trough adapted to collect oil flowing from the bearing surfacesof said eccentric and ring, and an oil pump arranged wholly within saidtrough at the point furthest removed from the center of rotation of saideccentric, whereby said pump may be substantially submerged in the oilat said point in said trough.

2. In a driving mechanism, the combination of a rotatable eccentric, aneccentric ring therefor, an annular lip extending outwardly and upwardlyfrom said eccentric and forming an annular trough, an oil collectingreservoir in said trough located at the point furthest removed from thecenter of rotation of said eccentric, a cam on said eccentric ring, apump in said reservoir comprising a plunger having a slotted crosshead,a rock lever adapted to be rocked by said cam, and an arm rigidlyconnected to said lever and cooperating with the slotted crosshead ofsaid plunger.

3. In a drivin mechanism, the combination of a rotata le eccentric, aneccentric ring therefor, an annular lip extendingoutwardly and upwardlyfrom said eccentric and forming an annular trough adapted to collect oilflowing from the bearing surfaces 44 and leads pump 10 to of saideccentric and ring, and a reciprocat- 1ng pump so arranged within saidtrough at the center of rotation of the point furthest removed from thecenter of rotation of said eccentric that the axis of its plunger istangent to the circular course which it travels with said eccentric.

4. In a driving mechanism, an eccentric, an eccentric ring therefor, atrough on said eccentric surrounding said ring and adapted to catch oilflowing from the bearing surfaces of said eccentric and ring, an oilpump fixed in saidtrough at the point furthest remove( from the centerof rotation of said eccentric, a cam on said ring, actuating means forsaid pump engaging said cam, and an oil conduit leadingfrom said-pumpthrough said eccentric and ring to said cam, the continuity of saidconduit being controlled by the relative movement of said eccentric andring.

5. In a lubricating mechanism a narrow chamber, means for passing oilinto said chamber, a pump within said chamber, said pump comprising abase, a cylinder arranged on said base a plunger adapted to bereciprocated in said cylinder and having a crosshead, two supportsarranged on said base and at opposite sides of said crosshead, a rocklever mounted on and between said supports and adapted to be rockedaround an axis at right angles to the axis of said plunger, an armrigidly connected to said rock lever at one end and cooperating at itsother end with the said crosshead. p

6. In a driving mechanism, an inner rotatable ring,a bearing surfacethereon, an outer non-rotatable ring on said bearing surface, a troughsurrounding said bearing surface to catch oil flowing from said bearingsurface, a pump in said trough, a conduit attached to said pump, saidpump removing the oil from said trough through said conduit.
